SPECIFICATION forming part of Letters Patent No. 276,597, dated May 1,188e.

Application filed March 3, 1 893. (No model.)

To all lwhom it may concern:

Be it known that I, FRANK J. KARLESKIND, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Stove- Pipe Thirnbles andF1ue-Stoppers,ot' which the following is a specification.

The objects of -my invention are to prevent smoke, soot, or impuritiesfrom the iue having egress in the room, also to avoid the use of nails,wedges, and similar fastenings, to avoid play of the thimble or `pipe inthe tine, es peciallyto achievea readyinsertion and proper iit of thepipe in the ue, and when said pipe is withdrawn or not used aself-closure of the thimble orilueopening. I attain these objects by themechanism illustrated in the accompanying drawings, in which` Figure 1is a front elevation of my improved thimble and fine-stopper as saidparts appear applied to the wall of a room in connection In said iigurethe slide door or stopper is shown as having closed the due-opening.Fig. 2 is a similar view, but showing the stopper raised to its highestposi tion, exposing the due-opening. In Fig. 3 the front plate isremoved, showing the thimble part only, consisting ofthe rear platehaving slot and thimble or sleeve and rivet-holes. Fig. 4 is a verticalsectional elevation, showing a section ot' the stove-pipe in thethimble. the stopper of the latter consequently in raised position, alsoshowing the manner of fastening the parts to the wall and flue and Hushwith the face of the ceiling.

Similar letters refer to similar parts throughout the several views.

My thimble, with its frames orhousing and Vself-closin g stopper, isintended as a permanent feature of a wall or stove-pipe flue.

A A' represent the frames, being chiefly a front or face plate and arear plate. Forming partot' the rear plate,A ,is the thimble properviz.,the metal sleeve B-to t snugly in the chimney-flue. (See Figs. 3, 4.) Atb this pla-te A' has an elongated slot, and along the ed gesot the plateare made rivet-holes. The front plate, A, has a circular opening, c, inline with the sleeve or thimble, so that the stove-pipe can be insertedinto the latter. (See Figs. 1,2,.4.) The upper portion of the plate A iscastwlatticed-that is, has the crossing-ridges, with the openings c',through which the portion ot' the stopper can be seen. (See Figs. 1, 2,4')

d represents transverse and vertical strips i of metal, eitherinterposed between the two pl'ates A A' or cast to project from the faceot eitherplate. (See dotted lines in Figz; also, see Fig. 4.) Thesetransverse and vertical stripsd separate the two plates A A from eachother and forni a space, D, between them to accommodate the operation'ofthe stopper. (See Fig. 4.) The arrangement of these strips d is near theedges ot' all the sides, so as to form transverse and vertical groovesd! around all the top, bottom, and opposite sides ol' the frames A A.(See Figs. 3 and 4.) It is in the groove d that the plaster can befitted and Y have a holdfast; also, the plaster (see X in Fig.

4) can be brought flush with the face ot' the front plate.

E is the stopper. Thisconsists simply of a plate of sufficient size toclose the due-opening. (See dotted lines in Figs. 1, 2.) The stopper Eis contained in the space D between the two plates A A. (See Fig. 4.)When the stopper is raised to its highest point it strikes against theupper transverse strip d, occupying the space behind the latticed-facedupper portion, clearing the due-opening for the insertion of thestovelpipe; but when thelatter is withdrawn or removed the stopper,byits own gravity, drops and closes the flue-opening, as shown` in Figs.1, 3. The opposite vertical strips d d (see dotted lines, Fig. 3) guidethe sliding of the stopper, and the opposite or top and bottomtransverse strips d estop the stopper at thosepoints. The stopper iskept raised by resting upon the stove-pipe. When the stopper drops itrests upon the bottom strip d. The two plates A A' are placed the onebehind the other, having the stopper E between them. 4In this conditionrivets e are passed through the plates and the strips d, (see Fig. 4,)

joining the plates and their parts together, asl

indicated.

The improved stove-pipe thimble and fluestopper is litted in the wall orchimneytlue, as shown. (See Fig. 4.) The thimbleB itself enuters theflue, and rests firmly against the brick wall by its flange B lappingdown inside the flue over the brick. Further, the frames or plates A A'are secured to the wall by passing a bolt, F, through the mortar, theslot b being elongated to permit the bolt F to reach the line ot' mortarbetween the bricks. This done, said boltu is finally fastened by a nut,f, as shown in Fig. 4. The plaster can be made to ll up the top, bottom,and opposite side grooves or spaces between the edges of the frames AA', and hence the whole device can be aflxed to the Wall or flue ushwith the face of the plaster.

The operation is simple, requiring only that d the stopper be raised toclear the opening ot' the thimble when the stove-pipe is to beinsertedorconnected. Whenthepipeisremoved out ot' the thimble thestopper selteloses the opening.

1. The improved stove-pipe thilnble and tinestopper consisting of thefront and rear plates, A A', having space D between them, the frontplate having a circular opening, the rear plate having the thimble Bproper,l with ange B',

and the interposed stopper E, all combined to operate as and for thepurposes set forth.

2. The improved stove-pipe thimble consisting of plates A A', the formerhaving a circlilar opening, c, the latter plate having the thimble B,both said plates riveted together and =having top, bottom, and oppositeside grooves formed by the spaces between their edges, by means whereofthe said plates and thimble can be filled Hush with the face of the wallor its plaster in line with the tine, as and for the purposes set forth.

3. The improved stove-pipe thimble and tluestopper consistingessentially of the frames or plates A A', the former having a circularopening, c, and the latticed upper portion, c', the latter plate, A',having thimble B,.with its anged rest-plate B', the slot b, the rodfastenin g F, the vertical and transverse interposed strips d, the top,bottom, and opposite side grooves formed bythe space between the edgesof the frames, and the sliding plate or stopper E, all combined tooperate in the manner-and for the purposes set forth.

In testimony ot' said invention I have hereunto set my hand.
